Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31527798, here are decompositions:

11 + 31527787 = 31527798
17 + 31527781 = 31527798
89 + 31527709 = 31527798
97 + 31527701 = 31527798
101 + 31527697 = 31527798
109 + 31527689 = 31527798
139 + 31527659 = 31527798
229 + 31527569 = 31527798

Showing the first eight; more decompositions exist.

IPv4 address
